Setting up: Real-time Ethernet (BK90xx, ADS/RAW, EAP polling)

Notes on the device

• An EAP (poll) adapter must be created in the configuration in order to operate a CU2508 downlink port as an EAP real-time Ethernet interface for IO devices (BK90xx, EK90x).
• The EAP (EtherCAT Automation Protocol) is operated here in the so-called polling mode
• At least TwinCAT 2.11R3 is required for operation on the master side.

Setting up the real-time Ethernet device

For the setup a real-time Ethernet adapter is to be created as usual.

Not an actual port of the PC, but rather a virtual adapter of the CU2508 is then merely selected as the Ethernet adapter for the CU2508.

The number of available ports (in this case 7) depends on the settings of the CU2508 device (see there).

Subsequently the required Ethernet couplers/boxes/drives can be manually added or scanned. Before a scan TwinCAT should be restarted once in the Config/FreeRun mode.
